Editor's Note: This is the last story of a Super Bowl series leading up to the big game, Feb. 2.

When the game clock runs out at the end of the second quarter of this Sunday's Super Bowl, another clock begins ticking as 1,500 workers have exactly seven minutes to get the halftime show stage television-ready for an estimated 108 million viewers.

Overseeing the well-rehearsed and precisely choreographed stage, video and audio setup for the halftime show for the fourth consecutive year is Wilton native Erik Eastland.

Eastland, the co-founder of Torrence, Calif.-based All Access Staging and Productions, which has been responsible for such large-scale events as the Super Bowl Halftime Show, the Grammys, the Daytime Emmy Awards and the Democratic National Convention, is no stranger to the precision required to pull off what seems like an impossible feat.

"When we hit 'go' it's all hands on deck. We've rehearsed this for the past two weeks, and everyone knows their job," Eastland said. "It could be something as simple as one person lifting a cap and the next guy moving the cap to the right."

Thirty percent of those 1,500 people work for various staging vendors, while the other 70 percent are volunteers who passed a 6-month screening process, according to Eastland.

In addition to setting up the stage, special effects lighting, scenery, and audio equipment must be in place for showtime. The 120-foot wide modular stage, which fills six truckloads, will be rolled out and assembled on the field in the first cold weather outdoor venue for a Super Bowl.

"The challenge may come from working outside in the elements. It could be 50 degrees when we rehearse and 50 below on game day, we're working under the pretext that we can be doing this in snow or rain," Eastland said. "In a normal indoor environment we have seven minutes to install the stage and get it camera ready. That can be stretched to nine minutes. It's the same time frame for this."

Eastland takes a philosophical approach to the challenges of the outdoor set-up of the highly-visible halftime show.

"It all comes down to weather, but we don't dwell on it," he said. "If the weather is bad during halftime that threatens things like choreography, but it also can add to the event. Do you remember when Prince was performing in Miami and during Purple Rain, it started pouring? It's that kind of thing that makes a show memorable."

High-profile events don't always go smoothly as evidenced by the power outage at the 2013 Super Bowl.

"During the Friday rehearsals before last year's Super Bowl, we decided to get off house power altogether," Eastland said. "We had to pull 18 miles of cable into generators. Everyone thought the halftime show blew out the power and it was cool for Beyonce to say that her performance blew out the power, but that wasn't the case."

Eastland's humble beginnings in show business began in the '70s as a young drummer for local band Rise, but he found that his true talent lay in the set-up for shows.

"I'm not sure they wanted me to continue being their drummer, so I started setting up the drumsets for shows, and I found I was really good at it," he said. "I got serious about it and began working with bigger bands."

In what he called his springboard into the big time, he worked with Alice Cooper, Edgar Winter and Rick Derringer.

"I then became the production manager and lighting designer for Al Jarreau," Eastland said. "In those seven years I learned a lot about lighting, staging, and sets."

Eastland started his own business in 1991, and in the last 22 years has set the stage for high-profile live entertainment acts and events such as: the Michael Jackson Memorial, the Coachella Valley Music & Arts Festival, the MTV Video Music Awards, the US Open of Surf and touring acts such as Billy Joel, Elton John, Madonna, Jay-Z, Eminem, Cold Play, Ricky Martin, Janet Jackson, Van Halen, Kanye West, Rihanna, and Without Warning.

"We've done all of the U.S. Olympics since 1984 as well as the Vancouver Olympics," he said. "At each event I take it all in and am still impressed by it all."

All Access Staging & Productions is a leading provider of portable rental stages and set construction services around the world and has provided rapid deployment staging.

"Proud of our status as a U.S. manufacturer, we have positioned our main headquarters and the hub of custom set fabrication in Los Angeles in close proximity to studios and major concert venues. We have additional U.S. offices outside of New York City and in the upper Northwest. Our international offices are located in London, Brisbane and Sydney. Like our hydraulic toasters, who knows where we'll pop up next?" according to All Access website.

"The Super Bowl is definitely one of the biggest for us," Eastland said. "I'll be there watching the game from the top of the rafters."
